Answer:

\Large \boxed{k=2x + \frac{-7}{3}} \\ \\ \\ \Large \boxed{x=\frac{1}{2} k+\frac{7}{6}}

Step-by-step explanation:

Solving for k:

\sf 3k+16=9+6x

Subtracting 16 from both sides.

\sf 3k=6x-7

Dividing both sides by 3.

\displaystyle \sf k=2x + \frac{-7}{3}

Solving for x:

Flipping the original equation.

\sf 6x+9=3k+16

Subtracting 9 from both sides.

\sf 6x=3k+7

Dividing both sides by 6.

\sf \displaystyle x=\frac{1}{2} k+\frac{7}{6}

Perimeter of a triangle is 27cm,if two sides measure 9cm and 7.8cm,find the measure of third side?
fredd [130]

Answer:

10.2cm

Step-by-step explanation:

Perimeter is the sum of the lengths of all sides.

1st side: 9cm

2nd side: 7.8cm

Perimeter: 27cm

Perimeter = 1st + 2nd +3rd side of a triangle

27cm = 9cm +7.8cm + 3rd side

3rd side = 27cm - 9cm -7.8cm

              = 10.2cm

Please help me! :) !!!!!!!!!!!!!!!!!
Novosadov [1.4K]

Answer:

x=17

Step-by-step explanation:

Since the triangles are congruent, the angles are equal

I≅ P  

3x+4 = 72-x

Add x to each side

3x+4+x = 72-x+x

4x+4 = 72

Subtract 4 from each side

4x+4-4 = 72-4

4x= 68

Divide by 4

4x/4 = 68/4

x = 17
